Minneapolis, May 29: Cheering protesters torched a Minneapolis police station that the department abandoned as three days of violent protests spread to nearby St Paul and angry demonstrations flared across the US over the death of George Floyd, a handcuffed black man who pleaded for air as a white police officer kneeled on his neck.

A police spokesman confirmed late Thursday that staff had evacuated the 3rd Precinct station, the focus of many of the protests, “in the interest of the safety of our personnel" shortly after 10 pm Livestream video showed the protesters entering the building, where fire alarms blared and sprinklers ran as blazes were set. Also Read | Afghanistan: 14 Afghan Security Force Members Killed in Attack Claimed by Taliban.

Protesters could be seen setting fire to a Minneapolis Police Department jacket. Late Thursday, President Donald Trump blasted the “total lack of leadership” in Minneapolis. “Just spoke to Governor Tim Walz and told him that the Military is with him all the way. Any difficulty and we will assume control but, when the looting starts, the shooting starts,” he said on Twitter. Also Read | Former Chhattisgarh CM Ajit Jogi Dies in Raipur: Live Breaking News Headlines & Coronavirus Updates, May 29, 2020.

Trump, who called protesters in Minneapolis “thugs,” drew another warning from Twitter for his rhetoric, saying it violated the platform's rules about “glorifying violence.”

A visibly tired and frustrated Minneapolis Mayor Jacob Frey made his first public appearance of the night at City Hall near 2 am Friday and took responsibility for evacuating the precinct, saying it had become too dangerous for officers there.

As Frey continued, a reporter cut across loudly with a question: “What's the plan here?” “With regard to?” Frey responded. Then he added: “There is a lot of pain and anger right now in our city. I understand that ... What we have seen over the past several hours and past couple of nights here in terms of looting is unacceptable.”

He defended the city's lack of engagement with looters — only a handful of arrests across the first two nights of violence — and said, “We are doing absolutely everything that we can to keep the peace.” He said National Guard members were being stationed in locations to help stem looting, including banks, grocery stores and pharmacies.

On Friday morning, the Minnesota State Patrol arrested a CNN television crew as they reported on the unrest in Minneapolis. While live on air, CNN reporter Omar Jimenez was handcuffed and led away. A producer and a photojournalist for CNN were also led away in handcuffs.

Fires burned Friday morning in Minneapolis and St Paul. Protests first erupted Tuesday, a day after Floyd's death in a confrontation with police captured on widely seen citizen video. On the video, Floyd can be seen pleading as Officer Derek Chauvin presses his knee against him.

As minutes pass, Floyd slowly stops talking and moving. The 3rd Precinct covers the portion of south Minneapolis where Floyd was arrested. Walz earlier Thursday activated the National Guard at the Minneapolis mayor's request. The Guard tweeted minutes after the precinct burned that it had activated more than 500 soldiers across the metro area.

A couple dozen Guard members, armed with assault-style rifles, blocked a street Friday morning near a Target store that has sustained heavy damage by looters. The Guard said a “key objective” was to make sure fire departments could respond to calls, and said in a follow-up tweet it was “here with the Minneapolis Fire Department” to assist. But no move was made to put out the 3rd Precinct fire. Assistant Fire Chief Bryan Tyner said fire crews could not safely respond to fires at the precinct station and some surrounding buildings.

Earlier Thursday, dozens of businesses across the Twin Cities boarded up their windows and doors in an effort to prevent looting, with Minneapolis-based Target announcing it was temporarily closing two dozen area stores. Minneapolis shut down nearly its entire light-rail system and all bus service through Sunday out of safety concerns.

In St Paul, clouds of smoke hung in the air as police armed with batons and wearing gas masks and body armor kept a watchful eye on protesters along one of the city's main commercial corridors, where firefighters also sprayed water onto a series of small fires. At one point, officers stood in line in front of a Target, trying to keep out looters, who were also smashing windows of other businesses.

Hundreds of demonstrators returned Thursday to the Minneapolis neighbourhood at the center of the violence, where the nighttime scene veered between an angry protest and a street party. At one point, a band playing in a parking lot across from the 3rd Precinct broke into a punk version of Bob Marley's “Redemption Song."

Nearby, demonstrators carried clothing mannequins from a looted Target and threw them onto a burning car. Later, a building fire erupted nearby. But elsewhere in Minneapolis, thousands of peaceful demonstrators marched through the streets calling for justice.

Floyd's death has deeply shaken Minneapolis and sparked protests in cities across the U.S. Local leaders have repeatedly urged demonstrators to avoid violence. “Please stay home. Please do not come here to protest. Please keep the focus on George Floyd, on advancing our movement and on preventing this from ever happening again,” tweeted St. Paul Mayor Melvin Carter, who is black.
